To aZZ whom t may concern:

Be it known that I, CHARLES S. LocK- WOOD, a citizen ofthe UnitedStates, residing at 289 Market street,"Newark, county of Essex, andState of New Jersey, have invented certain new and useful ImprovementsinRenewable Automobile Bearings, fully described and represented in thefollowing specification and the accompanying drawings, forming'a partofthe same.

The present invention relates to a rollerbearing for the rearaxle of anautomobile, in which a stationary bearing-tube is commonly supportedupon the frame of a carriage and the axle rotated by the power Withinthe same. By applying antifriction-rolls between the axle and thebearing-tube the friction of the movement is materially reduced; but thewear upon the bearing-tube ultimately prevents the rolls from operatingproperly and the bearing-tube rnust, therefore, be renewed unless adetachable liningsleeve be provided to sustain such Wear.

The object of the present invention is to furnish an economicalconstruction for such a detachable sleeve by which it may be readilysecured within the bearing-tubeand readily withdrawn and replaced incase of necessity.

In the present invention the sleeve is inserted in the outer end of thetube and the tube and sleeve provided with coincident perforations closeto the outer end, in which a stud or loose rivet maybe inserted to holdthe lining in position while in use.

A collar is provided to contact with the outer ends of theantifriction-rolls, and such collar may beutilized to hold the stud orrivet in the perforations. Whenever it is necessary to renew the lining,the removal of the collar permits the stud to be taken from theperforations and the lining to be withdrawn from the tube. The liningmay be formed with a collar at the inner end to hold the rolls therein,or a collar may be inserted in the tube and held in position by projcctions or studs upon the tube, and the collar at the outer end of thebearing may be provided with a socket to retain a packing which liesbetween the antifriction-rolls' and the wheelhub and prevents theintrusion of dirt into the bearing.

The invention will be understood by reference to theannexed drawings, inwhich-v Figure 1 is a longitudinal section, where hatched, of a bearingprovided With the improvements. native constructions for the innercollar, each view showing the half below the center line only. Fi 2 is alongitudinal section of ythe sleeve wit integral collar at the innerend. Fig. 3 is an end view of the same'- Fi 4 shows the inner end of thesocketed co ar. Fig. 5 is a section ofthe same, and Fig. 6 the outer endof the. bearing with the packing removed from the socket. Fig. 7 shows areverse arrangement for the collared liningsleeve.

a. designates the bearing-tube, which in practice is held stationary.

b is the axle, having the wheel-hub c secured removablyupon the outerend. The removable lining-sleeve d is shown inserted in the outer end ofthe bearing-tube, and a rivet e, having head e', is shown insertedthrough perforations in the sleeve and tube close to the outer end.Antifriction-rolls f are shown between the axle and the sleeve, and aseparate collar g is shown in Fig. 1 inserted in thetube between theinner end of the sleeve and two studs a', which are secured in holes inthe tube to hold the collar i'n place. An outer collar h is shown formedwith a cylindrical socket or chamber i, which `is fitted to the insideof the lining d and is provided at the outer end with a. flange y',wlich laps over the ends of the lining and tu e.

r One side of the socket is indented to form a recess k, (shown in Fig.4) which fits over the head e of the stud or rivet e and holds itimmovably so long as the collar is in place, as shown in Fig. 6. Thesocket, as shown in Fig. 1, serves to receive a charge of iibrouspacking Z, which prevents the access of dust and dirt to the interior ofthe sleeve and the antifriction-rolls. When the wheel is removed fromthe outer end of the axle, the socketed collar h i j can be removed fromthe Sleeve, which permits the rolls to be inspected or replaced, and therivet e can then be withdrawn from the perforations in the tube andsleeve and the sleeve replaced, if

i desired. The perforation in theV outer end of Fig. 1a and Fig. 1b showalter- IOO the sleeve is of great use in withdrawing the sleeve from theinterior of the tube, as a hooked tool can be engaged with theperforation to pull the sleeve out ofthe tube.

Fig. 1a shows an alternative construction for supporting the collar g inthe bearingtube by boring for a suitable depth to receive the sleeve dand the collar g, which is thus held in place by the shoulder g at thebottom of the bored recess. Fig. 1b shows another construction in whichthe collar g is formed with a flange h, secured Within the bearing-tubeby rivets i.

Fig. 2 shows the sleeve with an integral collar g2 upon its inner end,which serves-the same purpose'as the separate collar g in Fig. 1, butinvolves a more expensive form of sleeve than the straight tubularsleeve shown.

in'F ig. 1. This form of sleeve may be used without the detachablecollar h at the outer end of the bearing by reversing vthe separatecollar g and the sleeve within the bearingtube, as shown in Fig. 7, thecollar then serving to retain the rolls in the bearing in' place of thecollar h. This construction can e used with or without a packing betweenthe outer collar and the wheel-hub but the outer collar is shown evenwith the end ofthe bearing-tube in Fig. 7, so as to be held within thesame by contact with the wheel-hub.

From the above description it will be seen that the invention consists,broadly, of the combination, with the stationaryi .bearingtube, of thedetachable lining-sleeve having collar at the inner Vend and held fromlongitudinal movement within the bearing-tube by detachable meansWhic'hpermit it'to be withdrawn and replaced whenever necessary.

, Having thus set forth the nature of the invention, what is claimedherein is- 1. In. an automobile-wheel bearing, the combination, with thestationary bearingtube a, of the axle b rotatable therein and projectedfrom one end of the same with 'the wheelhub c secured detachably uponlthe projecting end ofthe axle, the lining-sleeved itted detachably inthe end of the bearingtube, the collars d and e fitted within the tubeat opposite ends of the sleeve with antifriction-rolls f fitted betweenthe same, and the wheel-hub c and the outer collar e being detachablefrom the sleeve and tube to permit inspection of the rolls,substantially as herein set forth.

2. In an automobile-wheel bearing, 'the combination, with the stationarybearingtube a, of the axle b rotatable therein and projected from oneend of the same with the Wheel-hub c secured detachably upon theprojecting end of the axle,.the lining-sleeve d itted detachably in theend of the bearingtube, the tube and sleeve having coincidentperforations near the outer end, the stud h held removably in suchperforations, the collars d and e at the opposite ends of the tube withantifriction-rolls f fitted between the same, and the Wheel-hub c andthe outer collar being detachable to permit inspection of the rolls,substantially as herein set forth.

3. In an automobile-bearing, the combination, withethe stationarybearing-tube'and the axle rotated therein;` of the detachablelining-sleeve d, vthe tube and sleeve having coincident perforations, astud held removably in such perforations, a collar held removably at theouter end of the tube and sleeve, and a separate collar iittedto 'theinner end 'of the sleeve 'within the tube, and projections upon the tubeholding such inner collar in place.

4. In an automobile-bearing, the combination, with the -stationarybearing-tube and the axle rotated therein, of the detachablelining-sleeve d, the tube and sleeve having coincident perforations, astud held removably in such-perforations, a collar at the inner end ofthe sleeve to retain the rolls therein, and a socketed collar at theouter end of the tu'be and sleeve to hold the rolls therein and providedwith packing in the socket, as and for the purpose set forth.

5,'. In an automobile-bearing, the combination, with the stationarybearing-tube and the axle rotated therein, of the 'detachablelining-sleeve d, the tube and sleeve having coincident perforations, astud inserted in the perforations and provided upon the inner end with ahead, a socketed collar fitted tothe outer end of the'tube and sleeveand formed with recess to engage the head of the stud, and the innerend' ofthe sleeve being' IOC provided with'a collar to hold the rollswithin v the sleeve. y

6. The combination of the stationary bearing-tube, the axle .rotatedtherein, the detachable sleeve within -the outer end ofthe tube, thesleeve and tube having coincident perforations near theouter-end, a'stude inserted in the perforations ha ving a head upon the inner end, andthe collar j having the cylindrical socket formed thereon with theflange and sleeve and the recess le in the outer side ofthe socket toengage the head e -of the stud, whereby the removal of thesocketedcollar ermits the removal of the stud and the withdrawal of thesleeve from the tube.

In testimony whereof I have hereunto set my hand yin the presence of twosubscribing :witnesses h fitted at the outervend of the tubev
